IMPROVEMENT IN PUMPS.

The Schedule referred to in these Letters Patent and making parte! the same.

To all whom' it may concern vBe it known that I, ROBERT L. WRIGHT, of West Nantmeal, in the county of Chester and State of Penn- Sylvania have invented certain new and useful Improvement in Pumps; and I do hereby. declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying `drawingand to the letters of reference marked thereon making part of this specification, in which.- Figure 1 is a longitudinal sectional view ofthe puinp and its operating mechanism.

Figure 2is a front View, showing the pump and arrangement of levers..

Figure 3 is a plan view of lever.

Figure is a plan view of washer-valve.

The' nature of my invention consists is so casting the cylinderof a force or .suck pump that broad `flanges are left at the point of its connection with the supply-pipe, the discharge-pipe, and the seat of the piston-rod; and, also, in securing, by means of diskplates on theiist two of said flanges, washer-valves, so arranged that the same arev readily opened by the pressure of the water; and in so securingon' the otherA disk a collar or sleeve that the escape ofthe water at the upper portion of the cylinder is prevented, and all waste and leakage securely guarded against.

The washer-valves, as well as the collar or sleeve,"

are constructed of ,leather or other like material, the former being circular in form, and providedavith a lip which lits closely over and entirely covers the openings to which the pipes are connected.

My invention also consists in constructing the discharge-pipe with an opening or jet, 'to prevent all danger of freezing; said opening or jet being provided with a pivoted cap, by means of which it can be opened or closed at pleasure. l

'My invention also consists in so arranging theupright that serves as the fulcrum on which the operating-lever works, inconnection with said lever, that an adjustable lever maybe used, and a single or doubleaction obtained as occasion may require, or a horizontal or upright leveiage obtained, at pleasure.

Among the numerous advantages possessed by' my pump may be enumerated its 'c lieapuess, portability, and simplicity of construction. lt can readily be seated and operated in any well, cistern, or stream, and itsA entire freedom from all complicated mec-lianism, either in its arrangement of valves or other features, and the lasting material of which it is constructed not only insures its successful'operation, but its durability, while by my arrangement of leverage, power-.can be multiplied as occasion requires.

. T6 enable others skilled in the art to make alud use my invention, I will now proceed to describe its construction aud operation.

ates rests, and through a suitable opening in which i the piston-rod` works. B is a cylinder, and may be constructed lof any suitable metal. This cylinder `is cast with three 4openings, one in'its upper, one in its lower section, and one at its side. The upper and lower openings are of the same diameter as the main chamber of the cylinder, while the side vopening is smaller.- f i Each of said openings is surrounded by circular flange-plates, as seen at b bibi.

The lower opening of the cylinder is lconnected with the supply-pipe O. This .supply-pipe O may be coustructed of any suitable material, and is provided with a circular flange, c, of the same dimensions, and the' exact counterpart of the ange b on the cylinder B.

These flanges b andl c are iirmly secured together by means'of bolts or screws c c'. The joint is rendered perfectly tight by means of the washer-valve D. This washer-valve D is constructed of leather or any other lsuitable flexible material, and has a portion of itscentral surface cut away, and is provided with a lip, d,

suilciently large to close the opening or passage between the cylinder B and pipe G.

The form of this washer-valve is clearly shown at fig. 4, where d2 represents the circular-formed slot on the surface of the washer, or the portion that is cut away.

The lip d is covered with a metal cap, d1, which not only strengthens the same, but whose weight presses the lip down closely, covering the opening until the pressure of the water elevates thesame, when an unobstructed passage is left'for the water.

E is the discharge-pipe, and may be constructed of..

any suitable material in the form shownat iig. l, or in any other desired. This pipe E is also provided with a flange, c, which corresponds exactly with the i iiange b2 of-the cylinder B; These flanges e and b2 are united by means of bolts or screws c' e. Between the same is inserted, and thus rendering the joint perfectly tight, a washervalve, D, constructed and arranged as before described.

This pipe E is also provided with an opening or jet, F, which is covered by a pivoted cap or cover, f.

This opening or jet is arranged at such a-point pn the pipe that, when the pump is.insertedin the vwell or frame casing A, it will be below the cover'A. It securely guards against all danger of freezing in winter or severe weather.

At a point above' the' section A the pipe E is provided with a short pipe or nozzle, G, having a female screw-thread cut'at its outer opening or mouth, lby

means of which can be firmly secured a hose or other discharge-pipe, g.

,At the upper end of the pipe E there is inserted a tight screw-plug, y', which prevents the escape of water at that point, and insures the discharge through the nozzle G.

H is a flatvmeta'llic disk of the same dimensions of the iiange b1 on the upper section of the cylinder I3.

On the under surface of this disk H, and around its center opening, is permanently secured, by means of a metal ring, h, a leather collar or sleeve, h1, through which works the piston-rod. Vhile this sleeve or collar h allows perfect freedom of motion to the pistonrod, still, at the sametime, it hugs the same sutiiciently close to prevent all waste or leakage at that point.

Between the disk H and the tia-nge bl is inserted a leather washer, which forms a perfectly tight joint when the disk is secured by the lscrews or bolts h2.

I is the piston-rod orplunger, 'and is provided at its lower section with a yoke, i, to which `is secured a valve-seatvor'bueket, il, on the upper surface of which is permanent-lyhinged a metallic vsuction-valve, t2.

This valve is provided with a leather washer, which insures its successful operation.

The yoke and valve are surrounded by a suitable jacket or sleeve, i, all of which is clearly shown in iig. 1.

J is an upright standard, which is firmly secured to the upper section of the frame, orthe cover of' the well A. The upper section of this upright or standard'is provided with a slotted head, j,'in,which is secured the operating-lever K.

The outer end of this lever is bolted t-o a short arm, L, which is secured to and operates the piston-rod I.

This lever K is provided with slotted caps 7c k, .in which can be insertedv an additional 1ever, K', when the same is considered desirable, or, instead of the system of leverageshown in fig. 2, an L-s'haped lever, such as shown in iig. 3, can be inserted and used.

of the levers at pleasure, and work the pump by means of either an upright or horizontal leverage. v

The plug g' and the hose g are so constructed that they can be made to exchange places, thus causing the pump to throw anupright stream instead of a horizontal one.

Having thus fully describedmy invention,

XVhat I claim therein as new, and desire to secure by Letters Patent of the United States, is-

A pump, consisting of the cylinder B, pipes C and E, the latter having jet F and cap f, and also being so arranged that the stream can be caused to issue I, washer-valves D D, and lever K, the whole being so arranged a's to operate substantially as described, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

Thus it will be seen that I can multiply the power either in a an upright or horizontal direction, plunger
